Prance1 1 Royal Botanic Gardens, Kew, Richmond, Surrey, TW9 3AB, UK Corresponding author: Ghillean T. Prance ([email protected]) Academic editor: Peter Stevens | Received 27 December 2013 | Accepted 4 September 2013 | Published 27 September 2013 Citation: Prance GT (2013) A new species of Licania (Chrysobalanaceae) from Cordillera del Cóndor, Ecuador. PhytoKeys 26: 71–74. doi: 10.3897/phytokeys.26.4590 Abstract A new mid altitude species of the predominantly lowland genus Licania, L. condoriensis from Ecuador is described and illustrated. Keywords Chrysobalanaceae, Licania, Cordillera del Cóndor, Ecuador Introduction A worldwide monograph of the Chrysobalanaceae was published in 2003 (Prance and Sothers 2003a, b). Some recent collections from Ecuador made in 2005 are of an undescribed species of Licania. This genus of 218 species is predominantly a lowland one and all three collections of this new species, L. condoriensis, are from an altitude of over 1,100 m. Table 1 lists 14 montane and submontane species of Licania that occur mainly at altitudes of over one thousand metres. Copyright Ghillean T. Prance.

Neill & W. Quizhpe 15076 (holotype K; isotypes, MO, QCNE). Small tree 3–7 m tall, young branches appressed puberulous, soon glabrous. Leaf lamina broadly ovate, 2.5–6 × 1.5–3.5 cm, subcoriaceous, acute or with short blunt acumen at apex, rounded to subcuneate at base, margins entire, glabrous and dull with densely reticulate prominulous venation above, with well-developed stomatal cavities beneath, the venation flattened around slit-like apertures of cavities, the venation glabrous and the cavities filled by a mass of white, unicellular simple hairs; veins 13–15 pairs, plane above, prominulous beneath; petioles glabrous, 3–10 mm long, rugose, with two sessile glands near apex. Stipules lanceolate, early caducous. Inflorescences short once-branched panicles 3–5 cm long, lateral branches borne at 90 degrees to rachis, the rachis and branches densely yellowish-brown tomentose. Flowers c 2 mm long, sessile or subsessile on primary branches of inflorescence; bracteoles oblong-triangular, acute, 1–1.5 mm long, tomentose on exterior and with ciliate margins. Receptacle campanulate, 1.5 mm long, yellowish-brown tomentose on exterior; calyx-lobes c. 1 mm long, acute, triangular, densely tomentose on ex- terior, tomentose within; petals absent; stamens 7–8, included, filaments equaling or shorter than the calyx lobes in length, c. 0.8 mm long. Ovary inserted at base of receptacle, unilocular with 2 ovules; style pubescent at base. Young fruit only seen, puberulous, glabrescent, unilocular. Additional specimens examined. Ecuador.

This distinct mid-altitude Licania belongs to Section Licania of the genus and is probably most closely related to L. compacta Fritsch from Roraima in Guyana, but dif- fers from L. compacta in the much less coriaceous, more acute leaves with a dull rather than shiny upper surface and in lacking the dense pubescence that covers the stomatal cavities of the latter and in the greater number of stamens. The leaves of L. condoriensis are very similar to those of L. octandra (Hofmanns. ex Roem & Schultes) Kuntze sub- A new species of Licania (Chrysobalanaceae) from Cordillera del Cóndor, Ecuador 73 Figure 1.

All collections of L. condoriensis are from the Cordillera del Cóndor for which this species is named. 74 Ghillean T. Prance / PhytoKeys 26: 71–74 (2013) Table 1.
